“The indoor world is far more dangerous than the outdoor world of which parents are so frightened, the almost non-existant stranger danger replaced by a real and insidious estrangement danger. Children, confined to their homes, become estranged from each other and from nature. Obesity, rickets, asthma, myopia, the decline in heart and lung function all appear to be associated with the sedentary indoor life.” – Geroge Monbiot,
